Exploration - West Africa - More luck in the golden triangle

Toronto-based Asante Gold has commenced its second-phase drilling programme at the company’s Keyhole Option in Ghana. Burwash Contract Drilling of Vancouver will complete 800m of diamond drilling to follow up on the high-grade gold discovery from drill hole MEM17-001B, which intersected 13.12 grams of gold (g/t Au) over 3.0m at a depth of 120m below the historical MEM showing.

According to Douglas R MacQuarrie, president and CEO at Asante, the intersection is in a north-east trending shear hosted in meta-greywacke/argillite, with quartz, sulfide, and visible gold mineralisation.

Location: Ghana
Resource: Gold

The Keyhole Option covers a 6km-long section of the Ankobra River and is strategically located at the intersection of three major regional gold mineralised trends:

  • The Asankrangwa Gold Belt, which hosts ~11 million ounces of gold resources at the Asanko Gold Mine (formerly known as PMI Gold Corporation’s Obotan Mine) and Esaase Gold projects, located 36km and 60km, respectively, to the north-east;
  • A major continental scale basement structure noted on regional aeromagnetic surveys, which is spatially related to the 66 million ounce AngloGold Ashanti Obuasi Mine and the 7.6 million ounce Newmont Akyem Mine, located 57km and 130km to the east-northeast; and
  • The north-trending Ankobra River lineament and its extensions, which connects 90km to the south of the +60 million ounces total resource gold mines at Bogosu, Prestea, and Tarkwa, operated by GoldenStar, AngloGold Ashanti, and Goldfields, with Newmont’s 15.3 million ounce Ahafo Mine 100km to the north.

Asante Gold is developing the Kubi Mining Lease and is exploring the Keyhole, Fahiakoba, and Betenase concessions, all adjoining or along strike of major gold mines near the centre of Ghana’s Golden Triangle.
